Scanty menstruation

Menstruation is one of the signs that a woman’s body is healthy and functioning correctly. When bleeding is excessive or minor, when it lasts too many days or lasts too few, and not to mention when the period does not come down, women feel very concerned. Certain variations are expected, and, despite these differences, the conception of pregnancy is possible. It is not to be alarmed. Scanty menstruation is also known as hypomenorrhea, and different causes can originate it.

In the following FastlyHealarticle, we will explain what menstruation usually looks like, when it is considered hypomenorrhea, and the causes of scanty menstruation.

How is normal menstruation?

Generally speaking, a woman is said to menstruate normally when she has a bleed every 28 days, approximately (with a variation between 21 to 35 days). That is, these intervals are always more or less the same.

On the other hand, the duration of bleeding is between 2 and 7 days (with an average of 5 days) and, finally, concerning the daily amount of blood, it is expected that they will drop by 30 to 40 ml and up to a maximum of 80 ml, which means using about six pads or tampons a day.

This is the case in most women, but it is also essential that you know that during the first years after the first menstruation, there is the usually more significant irregularity in terms of intervals, amount of bleeding, and even ovulation, since it has been seen that not it always ovulates in the first female cycles.

A very ecological and exciting way to get to know your cycle better is through menstrual cups. In addition to not generating waste using tampons or pads, you will know precisely hygienically and straightforwardly how much blood you eliminate, at what times, and its characteristics.

What is scanty menstruation?

As it is known medically, scanty menstruation or hypomenorrhea decreases the amount of bleeding or in the number of days that the period comes down. Still, in general terms, menstruation is regular. That is, every month, you bleed little or few days. This is very different, and the causes of oligomenorrhea, when the bleeding comes down every 45 days or more, are other.

In hypomenorrhea, bleeding usually decreases every 25 or 35 days. It can last less than two days or last more days but with slight bleeding. Total bleeding (of the entire menstruation) is usually less than 50 ml.

Causes of scanty menstruation

The endometrium usually causes the fact that menstruation is scarce (hypomenorrhea), is very thin, and is generally seen in the following cases:

Long-term use of oral contraceptives

Hormonal contraception methods, to prevent ovulation, make the endometrium not receptive to pregnancy, thus causing hypotrophy, that is, a thinning of the inner layers of the uterus, which are ultimately thickening and then falling cause menstruation. Therefore, if these are thin, the bleeding will be slight or last a few days.

Endometrial alteration due to excessive curettage

It may be that during an abortion, a curettage or scraping of the uterine walls has been performed in an exaggerated way, with which the structures of the uterus are damaged, which are the ones that thicken every month and then fall as menstruation.

Sinequias uterine

The word synechia refers to the formation of one or more scars inside the uterus, generally due to procedures performed within these: intrauterine surgeries, curettage, etc.

Generally, synechiae can also be seen on ultrasound or other methods such as hysterography or fiberscope. The first is through a contrast liquid placed in the uterus, then X-rays are taken, or the second with a tiny camera that observes how the uterine structure is direct.


There may be some light bleeding during the first months of pregnancy that could be confused with menstruation. Therefore, if this has happened to you recently and you think there is a possibility of pregnancy due to having had unprotected sex, then it is convenient that take a pregnancy test.

Eating disorder

Eating problems such as bulimia and anorexia usually cause problems in the menstrual cycle. Although the most common is that the lack of menstruation occurs directly (known as amenorrhea), it may also happen a hypomenorrhea or menstruation in drops or little.


It is an infrequent cause, and it is the low amount of estrogens. Estrogens are precisely the hormones responsible for producing the thickening of the endometrium, so necessary to produce normal menstruation. Light menstrual bleeding can occur when these estrogens are in insufficient quantity, known as primary hypomenorrhea. There has been no other factor causing the endometrium to be thin, only low estrogen hormones.

First, to determine that this is the problem, the other causes are ruled out. The solution given by gynecologists is through estrogen medication in the last 7 to 10 days of the cycle.

Whatever the cause of scanty menstruation, it is imperative to correct daily habits in terms of exercise and eating since it has been seen that it is critical to help regularize female cycles. Performing at least 30 minutes of daily exercise (walking, dancing, swimming, etc.) help to achieve balance in the body. The same happens when a healthy diet is acquired: water instead of sugary drinks, with sweeteners or alcohol, raw fruits, and vegetables, nuts, honey, seeds, fermented, etc., should be the basis of the meals for in this way to be able to function normally and to promote the cure of diseases.
